Borrello was making his 12th club appearance against Jamie Maclaren's former club, SV Darmstadt.

The scores were locked 0-0 at the break, when Strasser reportedly started to feel very unwell. The club later confirmed he was rushed to hospital, with what the German media are reporting was a heart attack.

Strasser took over at Kaiserslautern in September, following the sacking of Norbert Meier. Strasser has shown much mroe faith in Borrello than his predecessor, who barely played the Australian, featuring the Aussie as part of a pacey, dynamic front third.  

Borrello has already racked up four assists for his new German club, in contrast to the other Aussies who have been struggling for game time in the German divisions this season.
